Plasmids can be passed along to help other bacteria use new ? sources and they can pass along a code for ? to drugs and production of ? and ?
|
food
resistance toxins enzymes |
|
|
Because plasmids are readily ? in the lab and transferred from one bacterial cell to another, they are an important agent in modern ? techniques
|
manipulated
genetic engineering |

Inclusions are also known as Inclusion ?
|
bodies
|

|
|
Polyphosphate granules of Corynebacterium and Mycobacterium are called ? granules because they stain a contrasting color in methylene blue
